Answer 2

1. Open PowerShell or terminal and run java -version to make sure Java is installed

2. Go to Apache Maven's download page and, if you're using Maven just as a tool, download the "Binary zip archive" from the link

3. Place the downloaded file in the folder where you have all your Java related things (in my case, C:\Program Files\Java)

4. Right click in that file and "Extract here". Then, delete the .zip file.

if we open that new folder we should have something like

5. Go to advanced system settings (by searching for that term or right clicking in "This PC" > Properties) and "Environment variables".

6. Define a new System Environment Variable by clicking New and

Variable Name: M2_HOME

VARIABLE VALUE: C:\Program Files\Java\apache-maven-3.6.3

7. Append the bin subdirectory of the folder C:\Program Files\Java\apache-maven-3.6.3 into the PATH variable

8. Restart your computer and then run mvn --version.

That's it, you have now Maven installed in Windows 10.
